ATTORNEY Patented Dec. 30, 1952 HEADREST Philip Challis, London, EnglandApplication November 4, 1949, serial No. 125,499 In Great BritainNovember 5, 1948 6 Claims. 1

for attachment to the back of a chair comprises a pair of frames ofmetal or the like pivoted together at their upper ends and adapted to besprung apart at their lower ends to grip over the back of the chair andat the same time firmly to hold a removable cushion or the like at theirupper ends so that said cushion or the like is supported above the backof the chair to serve as a head rest.

In the accompanying drawings illustrating forms of head rest constructedin accordance with the present invention:

Figure 1 is a perspective view of one form of head rest;

Figure 2 is a sectional side elevation of the same with the cushion andchair back illustrated by dot and dash lines;

Figures 3 and 4 are similar views of a modification;

Figure 5 is a side view of the device incorporating locking means forthe lower ends; and

Figure 6 is a side elevation of a locking device.

In the form of the invention shown in Figures 1 and 2 a head restattachment adapted to removably hold a cushion or the like above theback of a chair comprises a, pair of substantially rectangular frames A,13 made of metal rod or wire and pivotally connected together at theirupper ends at C and D.

The frame A adapted to engage at its lower end over the back of a chairE indicated in dot and dash lines comprises a lower part F of U- formprovided at each of its upper ends with a pair of pivots G, H to whichare pivotally attached pairs of upper side pieces J, K disposed more orless parallel to each other. The upper ends of the side pieces, J, K arepivotally attached at C, D to the upper part of the other frame B.

The frame B consists of a horizontal lower portion L bent upwardly ateach end to form side members M which are cranked rearwardly at N atboth sides to rest on the top of the chair back. The upper end of theside members M are extended rearwardly at 0 where it is connected to thepivots C, D. The rear ends of the portions 0 are bent downwardly at Pand connected together by a cross bar Q. A further cross bar R connectsthe portions 0 at points situated between the two pivots C and D.

The rear side pieces K of the frame A are cranked downwardly at S andconnected by a cross bar T. The lower cross bar of the U-frame F isbowed outwardly at the middle as shown at F Cross bars Q and T, both ofwhich are offset from the pivots D at the rear of the frames, constitutejaws for gripping a cushion, and also constitute stops for limitingswing of the frames in direction of swinging the lower ends apart.

In use the bowed portion F of the frame A is moved rearwards withrespect to the lower part of the frame B so that the chair back E isgripped between the lower parts of the two frames as shown in Figure 2.This movement of the frames presses the two cross bars Q and T togetherso as to grip between them the upper edge of a detachable cushion or thelike V which is thereby held in position over the front of the frames toserve as a head rest to the occupant of the chair as shown in Figure 2.

In the modification shown in Figures 3 and 4 the frame A is made withoutthe double side pieces and consists of a rectangular frame of metal rodor wire having the lower side F bowed as before while the side members JJ are cranked at S and connected by a cross bar T The frame A is pivotedat C to the upper part of the other frame B which consists of a metalstrip or bar comprising a lower horizontal portion L bent upwards toform side members M cranked rearwardly at N and twisted through at W.The upper ends of the side members M are curved over as shown at X wherethey are connected together by a pair of cross bars Q and R disposed atopposite sides of the pivot C The device shown in Figures 3 and 4 isused in the same way as that shown in Figures 1 and 2 so as to supportthe cushion or the like V above the chair back E as indicated by dot anddash lines in Figure 4.

Figures 5 and 6 show a locking device for preventing the lower ends Fand L from opening out by leverage on the chair back. This devicecomprises a turn buckle A which is rotatably secured to the frame B at Bby means of a pin B This turn buckle A supports a spiral wedge A so thatwith the device mounted upon a chair back the turn buckle may be turneduntil the wedge bears against the frame member A In this position theframe members A and 13 cannot at their lower ends move further apart toallow the device to be levered off the chair back. In the position shownin full line in Figure 5 the members A and B are spread at theirmaximum, opening and are prevented from moving further open by thenarrow end of the wedge A In the position shown in dotted line the framemembers have their lower ends closed to a minimum in which case thethick end of the Wedge bears against the frame member A In Figure 6 theturn buckle is shown off the device to show the form of spiral wedge.

Having now particularly described and ascertained the nature of my saidinvention I declare that what I claim is:

1. A head rest for attachment to the back of a chair, comprising a pairof frames, pivots connecting the frames next their upper ends wherebythe frames can be swung apart at their lower ends to grip over the backof a chair, said frames having means next the pivoted ends limitingextent of swing on said pivots in direction of swinging the lower endsapart, said means providing cooperating jaws spaced from the pivots andat the rear of the frames adapted to hold a removable cushion andthereby support said cushion above the back of the chair to form a headrest.

2. A head rest in accordance with claim 1, wherein said means compriseslongitudinally engageable cross-members, one on each frame, adapted topinch said cushion therebetween from side to side of the frames.

3. A head rest in accordance with claim 1,

wherein said means is located substantially intermediate of the line ofsaid pivots and chairgripping lower ends of the frames.

4. A head rest in accordance with claim 1, wherein each side arm of oneframe comprises a substantially parallel pair of members with two pivotsat each end.

5. A head rest in accordance with claim 1, wherein one frame isformedlwith single side pieces and the other is formed from a bar havinga substantially semi-circular hook at its upper end with the pivotsmounted in the uppermost part thereof,

.6. A head rest in accordance with claim 1, wherein is provided alocking means between portions of the frames for retaining the frames inchair-engaging position.
